Description
the Apollo model RPLF 4A lead free reduced pressure principle backflow preventers consist of two independently acting, TriForce™ center stem guided check valves with a differential pressure relief valve located between the check valves. the unit is designed to give maximum protection against backflow of health or non-health hazard fluids by either back-pressure or back-siphonage. the durable domestic stainless steel units (2-1/2”-8”) and the FDA epoxy coated ductile iron units (10” and 12”) are easily maintained in the line without any special tools. the TriForce™ check valves operate with a spring assist in the flowing condition to provide excellent flow rates which are documented by an independent laboratory.
